Seeed Studio Raspberry Pi Pico RTC DS3231 Precision Module

The Seeed Studio Precision RTC Module for Raspberry Pi Pico is a high-accuracy real-time clock expansion board designed specifically for the Raspberry Pi Pico series. Powered by the renowned DS3231 chip from Analog Devices, this module provides exceptional timekeeping precision with temperature-compensated performance, ensuring reliable time and date tracking for your projects.

Communication is handled via the I2C bus, making integration straightforward with Raspberry Pi Pico boards using standard headers. The module's compact, stackable design allows you to connect additional external sensors without sacrificing space, making it a versatile addition to your development setup.

The DS3231 RTC provides comprehensive timekeeping functionality, including seconds, minutes, hours, day of month, month, day of week, and year, with leap-year compensation valid until the year 2100. You can choose between 24-hour or 12-hour formats, with an AM/PM indicator for the latter, and utilise two programmable alarm clocks for scheduled events or wake-up calls.

The module includes a backup battery holder to maintain timekeeping during power loss, ensuring your clock remains accurate even when unpowered. Comprehensive development resources and a manual are provided, featuring Raspberry Pi Pico C/C++ and MicroPython examples, to accelerate your development process.

Please note: The Raspberry Pi Pico board is not included with this module.
